• Do not use this heater for heating human living
quarters.
• Do not use in unventilated areas.
• The flow of combustion and ventilation air must not
be obstructed.
• Proper ventilation air must be provided to support
the combustion air requirements of the heater
being used.
• Refer to the specification section of the heater’s
manual, heater dataplate, or contact the factory to
determine combustion air ventilation requirements
of the heater.
• Lack of proper ventilation air will lead to improper
combustion.
• Improper combustion can lead to carbon monoxide
poisoning leading to serious injury or death.
Symptom of carbon monoxide poisoning can
include headaches dizziness and difficulty in
breathing.

A. The Mr. Heater MH30T and the MH30TS are high pressure
propane appliances and are designed to be connected to a bulk
propane tank. Every unit is tested during manufacturing and
shipped fully assembled except for bulk tank.
B. These heaters are equipped with two automatic Safety Shutoff
Valves. The gas flow will automatically stop to the heater burner
if that heater burner fails to operate for any reason.
C. Maximum safety and convenience have been built into the Hi-
Med-Lo-Off Control Valve/Regulator. The following table lists the
approximate BTU’s consumed and the operating hours you can
reasonably expect from bulk propane cylinders. Fig. 2.
D. Model MH30TS is equipped with “Sparklite” igniters for
convenient heater lite-off.

Do not take any action that could ignite the fuel gas. Do
not operate any electrical switches. Do not pull any power
supply or extension cords. Do not light matches or any
other source of flame. Do not use your telephone.
Get everyone out of the building and away from the area
immediately.
Close all propane (LP) gas tank or cylinder fuel supply
valves, or the main fuel supply valve located at the meter if
you use natural gas.
Propane (LP) gas is heavier than air and may settle in low
areas. When you have reason to suspect a propane leak,
keep out of all low areas.
Use your neighbor’s phone and call your fuel gas supplier
and your fire department. Do not re-enter the building or
area.
Stay out of the building and away from the area until
declared safe by the firefighters and your fuel gas supplier.
FINALLY, let the fuel gas service person and the firefighters
check for escaped gas. Have them air out the building and
area before you return. Properly trained service people
must repair any leaks, check for further leakages, and then
relight the appliance for you.
ODOR FADING - NO ODOR DETECTED
Some people cannot smell well. Some people cannot smell
the odor of the man-made chemical added to propane (LP)
or natural gas. You must determine if you can smell the
odorant in these fuel gases.
Learn to recognize the odor of propane (LP) gas and
natural gas. Local propane (LP) gas dealers will be more
than happy to give you a scratch and sniff pamphlet. Use it
to become familiar with the fuel gas odor.
Smoking can decrease your ability to smell. Being around
an odor for a period of time can affect your sensitivity to
that particular odor. Odors present in animal confinement
buildings can mask fuel gas odor.

colorless and the intensity of its odor can fade under
some circumstances.
If there is an underground leak, the movement of gas
through the soil can filter the odorant.
Propane (LP) gas odor may differ in intensity at different
levels. Since Propane (LP) gas is heavier than air, there may
be more odor at lower levels.

Propane (LP) gas has a distinctive odor. Learn to recognize
these odors. (Reference Fuel Gas Odor and Odor Fading
sections above.
Even If you are not property trained in the service and
repair of the heater, ALWAYS be consciously aware of the
odors of propane (LP) gas and natural gas.
If you have not been properly trained in repair and service
of propane (LP) gas then do not attempt to light heater,
perform service or repairs, or make any adjustments to the
heater on the propane (LP) gas fuel system.
A periodic sniff test around the heater or at the heater’s
joints; i.e. hose, connections, etc., is a good safety practice
under any conditions. If you smell even a small amount of
gas, CONTACT YOUR FUEL GAS SUPPLIER IMMEDIATELY.
